Rewrite the fraction in the sentence below as a percentage.At a certain wedding, 3950 of the guests were under 65 years old.Percentnotation:%

To convert the fraction of guests under 65 years old into a percentage, we can follow these steps:

1. ### Break Down the Problem

We need to determine the percentage of guests under 65 years old compared to the total number of guests.

2. ### Relevant Concepts

The formula to convert a fraction to a percentage is: $\text{Percentage} = \left( \frac{\text{Part}}{\text{Total}} \right) \times 100$ Where:

• Part = number of guests under 65 years old
• Total = total number of guests at the wedding

3. ### Analysis and Detail

Assuming that we have the total number of guests at the wedding, we will proceed by substituting $\text{Part} = 3950$ and calculate with $\text{Total}$.

Let's denote the total number of guests as $T$. Thus, the percentage of guests under 65 years old becomes: $\text{Percentage} = \left( \frac{3950}{T} \right) \times 100$

4. ### Verify and Summarize

To complete the answer we need the total number of guests. Assuming it is provided, we can calculate the percentage.

Final Answer

If the total number of guests $T$ is known, simply substitute it into the formula above to find the final percentage. For example, if there were 5000 guests in total: $\text{Percentage} = \left( \frac{3950}{5000} \right) \times 100 = 79\%$ Make sure to replace $T$ with the correct total when you perform the calculation.
